Ausir was an Elf of Tol Eressëa according to the early version of the legendarium in The Book of Lost Tales. He was one of the children in the Cottage of Lost Play, and he told Eriol of the fate of Huan the Hound, and revealed to him that the old man whose guidance brought him to the Lonely Isle was none other than Ulmo himself. He argued with Vëannë, suggesting elvish names Tinwë Linto and Wendelin instead of Gnomish Tinwelint and Gwendeling.
